Megger MTB7671/2 Instrument Test Box
Instrument test boxes have an important role to play in guaranteeing the reliable test results needed to ensure the safety of electrical installations.
The Megger MTB7671/2 is designed to provide confirmation that your testers continue to operate properly, and maintain their accuracy and consistency between calibrations.
With the Megger MTB7671 instrument test box you can test the insulation resistance, continuity, earth loop impedance, PFC, RCD and voltmeter functions of you testers quickly and easily, recording the test results on the record cards included in the pack. There are also self-adhesive test labels for your tester.
FEATURES
Does not trip RCD protected circuits.
Tests to regulations BS7671, BS EN61557 & IEE On-Site Guide.
Checks insulation, continuity, loop, PFC & RCD functions.
Check of any voltage measurement ranges on the instrument.
